I always have mixed feelings about that kind of an attitude, at times it feels like this is making excuses, so you can still watch something involving horrible people without feeling guilty about it.
Who a person is and what they do are two different things. I can't know if the people who bag my groceries or who built my car ever did anything vile or criminal, and it would make no difference to my life anyway, because the jobs they perform are not about who they are in their personal lives. Acting creates the illusion of a more direct, intimate connection to a person, but it's still just an illusion. It's still just a job they do, nothing more.
And the same person can do both good things and bad things. It makes no sense to try to reduce an entire complicated human being to a single variable. I don't see how appreciating the good things someone did equates to excusing or endorsing the bad things, and I don't see how rejecting the good things helps with the bad things.
If I boycotted anything created by a person who'd done bad things, I'd have to throw out
Star Trek because of Gene Roddenberry's sexual predations and generally jerky behavior to his collaborators. I'd have to throw out most of DC Comics because Julius Schwartz was a horrible sexual predator and misogynist. I'd have to throw out Isaac Asimov's canon for his decades of sexual harassment. I'd have to throw out the Hitchcock canon because of his atrocious behavior toward his actresses. I'd have to throw out the first
Doctor Who because William Hartnell was a racist. Most of the stuff I love was created by problematical people. But I don't see how it would make things any better if I rejected the good things they'd done.
We don't blame children for the sins of their parents. So should we blame people's brainchildren, the books they write, the shows and films they make, and the roles they perform onstage, for the sins of their creators? Once a work is out there, it has its own life independent of its creators, because its meaning becomes a function of what its audience chooses to see in it.
But I don't overlook or excuse what the bad person did.
And nobody said you should. Some people are just rushing to assume that's what the interviewee meant, instead of making the effort to find the original context.
